AXLE-NUT.

Specification of Letters Patent.

Patented. Dec. 10, 1907.

Application filed November 5. 1906. Serial No. 342,097.

To all whom it may concern:

Be it known that I, NOBLE Ron, citizen of the United States, residing atMarceline, in the county of Linn and State of Missouri, have inventedcertain new and useful Improvements in 'Axle-Nuts, of which thefollowing is a specification.

This invention is designed to provide an axle nut of peculiar formationwhich will admit of taking up wear between the axle box or hub and theshoulder and nut applied to the axle arm, thereby preventing rattlingand play of the Wheel upon its spindle.

The invention consists of an axle nut formed of sections and one or morewashers adapted to be interposed between said sections, therebyadmitting of varying the distance between the. flange and the threadedor cap members comprising the axle nut.

The invention further consists of an axle nut having a box projectedfrom the flange member to receive the cap or threaded member, andretaining lips rojected from the box and adapted to be ent over'said capor threaded member to retain the parts in place when the axle nut isremoved from the axle arm or spindle. V

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction and the meansforeffecting the result, reference is to be had to the followingdescription and accom anying drawings.

Whi e the invention may be adapted .to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereo still the preferred embodiment isshown in the accompanying drawings, in which:

Figure 1 is a central longitudinal section of an axle arm or spindle andaxlebox provided with an axle nut constructed in accordance with thisinvention. Fig. 2 is a view similar to Fig. 1 of the outer portion ofthe axle arm, showing a series of washers interposed between the cap andthe flange. Fig. 3 is a detail perspective view of the axle nut, theseveral parts being separated and relatively arranged in a group.

Corresponding and like arts are referred to in the followin descriptlonand indicated in all the views 0 the drawings by the same referencecharacters.

The axle arm or spindle and the axle box may be of any make and areillustrated to show the application of the invention. The axle arm orspindle 1 is provided at its inner end with the usual shoulder 2 andguard 3 and its outer end is reduced and threaded to receive the axlenut. A leather washer 4 is slipped upon the arm or spindle and bearsagalnst the shoulder 2 and comes between said shoulder and acorresponding form at or near the inner end of the axle box 5. The axlebox 5 is of ordinary construction and is provided at its inner end withan enlarged portion 6 which encircles the shoulder 2 and underlaps theflange of the guard 3, thereby excluding mud and other foreign matter.

The axle nut constituting the basis of the present invention is formedof two parts,

flange 7 is recessed upon one face to receive a washer 9 which is adated to abut against the outer end of the ax e box 5 and act inconjunction with the washer 4 to prevent play of the box or wheel uponthe arm or spindle. A box 10 is formed upon the opposite face of theflange and is adapted to receive the cap 8 and form ahousing therefor.Retaining lips '11 project beyond ends of the boX 10 and aresufliciently flexible to be bent over the cap 8 to retain the samewithin the box and prevent accidental separation of the arts 7 and 8when the axle nut is removed om the arm or spindle 1.

As shown, the plates 12 have their inner ends inserted within the boxand their inner terminal portions are passed through slots 13 in thesides of the box and are then bent against the outer sides of the box soas to.

retain the metal plates in proper position. This constructon admits ofreplacing the retaining lips, should they become broken by frequentbending necessitated by removal of the cap 8 either to place spacerWashers in position or to remove the same as occasion may require.

The cap 8 or threaded member of the axle namely, the flange 7 and thecap 8. The

to be inserted in the box and come between the flange and the member 8to hold the parts in proper position. 14 may be of any thickness and oneormore The spacer washer may be employed as may be found necessary. I

When fitting a wheel to an axle arm or spindle andit is found that thereis too much play between the ends of the axle box and the shoulder andaxle nut, the latter is removed and a spacer washer 14 of properthickness or two or more spacer washers are placed in position, thethickness being determined vby trial or ascertained in any way. Theopening in the flange member 7 and in the spacer washer is of a diameterto receive the end portion of the axle arm or spindle adjacent to thereduced threaded portion, hence the cap or threaded. member 8 is adaptedto screw tight upon the threadedend of said axle arm orspindle andpresses the spacer washer and flange member against the outer end of theaxle box. The angular formation of the member 8 and the correspondingformation of the box 10 prevents relative turning of the parts 7 and 8when fitted together.

When the box becomes worn the wear or slack is taken up either byintroducing a thicker washer 14 or by placing one or more washers inposition between the cap and flange of the nut, as indicated mostclearly in Fig. 2. To remove the cap 8, the lips 11 are straightened andafter the cap and flange are placed together, they are secured bybending the lips 11 over the outer end of the cap. The construction issuch as to admit of the retaining lips being readily replaced by-newones should they become broken or unserviceable from any cause.

Having thus described the invention, what is claimed as new is:

1. An axle nut comprising separable flanged and threaded members, andretaining means for securing the p arts when placed together andindependent of each of said parts and comprising bendable portions inpositive engagement with both the said flanged and threaded members.

2. An axle nut comprising separable flanged and threaded members, one ofthe parts having a slot, a plate having an end portion passed throughsaid slot and. bent and having the opposite end of said plate bent toengage with the other member or part of the nut.

3. An axle nut comprising a flange having a socket and having a slot ina wall of the socket, a plate having an end portion placed within thesocket and its extremity passed through the said slot and bent and athreaded member inserted in the socket of the flange and confining theplate therein, the projecting end of said plate being bent to engagewith the outer end of said threaded member.

4. An axle nut comprising a flange having a box upon one side and havingslots in the sides of the box, plates inserted in said box and havingend portions passed through. the slots thereof and bent, and a threadedmember fitted within the box and confining the said plates therein, saidplates having their outer ends bent to engage over the outer end of saidthreaded member.

In testimony whereof I aflix my signature in presence of two witnesses.
